What happen to the housefly after being trapped in a airtight containet?

When a housefly is trapped in an airtight container, it will eventually die due to a lack of oxygen. Flies require oxygen to survive, and without a source of fresh air, they can suffocate. Additionally, the buildup of carbon dioxide and other waste products in the confined space can further contribute to their demise. This process typically occurs within a few hours to a couple of days, depending on the size of the container and the initial conditions inside.
